SHIP LOADING OR COALING DEVI CE.

SPECIFICATION forming part of Letters Patent No. 739,033, dated September 15, 1903.

Application filed April 23, 1903. Serial No. 153.929. (No model.)

To all whom it may concern.-

of the Emperor of Austria-Hungary, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvementin Ship Loading or Ooaling Devices, of which the following is a specification.

My invention relates to a new and useful improvement in apparatus for loading and unloading vessels, and is intended, primarily, for the purpose of coalin g vessels while at sea, and has for its object to provide an apparatus which will be carried by the collier and which apparatus may be connected with another vessel or to the land, so that coal may be transferred from one point to another, to be operated entirely from the vessel carrying the apparatus.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specficially designated by the claims.

In order that those skilled in the art to which this invention appertains may underderstand how to make and use the same, the

of a portion of the mast of the vessel to which the apparatus is secured, showing the construction of the weight for keeping the cable upon which the traveler runs taut; Fig. 7, a plan view of one of the weights.

Upon the vessel which carries the apparatus is arranged a boom A, pivotedrso as to swing on the pivotal point B. This boom is supported by a guy-rope or cable C, which extends from the upper end of the boom over a pulley Don the mast and extends downward and is secured to the lower end of the mast in any suitable manner, as represented at E. This guy-rope O is for the purpose of Be it known that I, JULIUS TARR, a subject,

raising or lowering the boom, and there are guy-ropes or cables F extending from the upper end of the boom upon each side for the purpose of holding the boom against swinging and regulating its position.

G isa cable upon which the traveler H runs,

and the outerend of this cable is designed to be carried to the end of the vessel to be coaled or to a point upon the land and secured-in any suitable manner; but this end of the cable must necessarily be secured at a point lower than the upper end of the boom, so that the traveler will run downward upon an incline. The cable G extends over a pulley A, journaled upon the boom, and over a pulley I, journaled upon the mast, and to this end of the cable is secured a weight J, designed to always keep the cable G taut, as the swaying and movement of the vessels will necessarily shorten and lengthen the cable, and this weight will always keep the cable taut, so that the traveler may be free to run upon the same.

The weight J consists of two upright rods J,

secured together at the top and bottom by the cross-pieces J The cable G is secured to the upper cross-piece.

K represents disks which form the weight. Each one of these disks is provided with snaphooks K upon each side, which may be snapped upon the rods J.

L is a rod extending vertically parallel with the mast and secured to the mast rigidly at the top and bottom. This rod passes through the cross-pieces J and guides the framework in its movement. The disk Weights are slotted at the point K so as to straddle this rod L when placed in the frame.

The traveler H consists of a framework in which are journaled the rollers M, which rest upon the cable G.

N is a drum journaled in the framework of the traveler.

O is a cable secured at one end to the framework of the traveler H, and this cable then passes downward around the pulley of a block P, then over a pulley Q, journaled in the framework of the traveler, and then' passes with oneor more turns around the drum N and from there to a pulley R, secured to the boom, and from this pulley downward to a winding apparatus, such as a capstan or steam-winch S, located upon the deck of the vessel carrying the apparatus. To the block P is secured a hook P, to which is suspended the bucket P which conveys the coal or other material. Secured to the same shaft as the drum N is a ratchet-wheel T.

T is a spring-pawl normally in engagement with the ratchet-wheel, and T and T are levers pivoted to the framework, adapted to operate so as to raise the pawl from out of engagement with the ratchet-Wheel.

U is a trip secured to the upper end of the boom, and this trip is arranged in such a position that when the traveler is forced against the boom this trip will depress the heel end of the lever T so as to raise the pawl T out of engagement with the ratchet-wheel.

V is a spring-latch adapted to slide parallel with the boom and guided thereon, this latch having a beveled nose, and when the projection II, extending downward from the traveler, strikes this beveled surface it will depress the latch and pass behind the same, when the latch will spring back into its normal position, holding the traveler against the boom until released. At the lower end of the rod V, to which the latch is attached, is secured a rack V which is adapted to be operated upon by the segmental gear V whereby the latch may be raised and lowered.

In operation after the outer end of the cable G has been secured to the land or another vessel and the traveler II is held by the latch V against the boom the bucket P is lowered to the deck or hold ofthe vessel, and by slackening up on the cable 0 the bucket P is allowed to be lowered, because when in this position the pawl T is out of engagement wit-h the ratchet-wheel T, thus allowing the ratchet-wheel to turn with a retrograde movement. After the bucketlhas been filled then by pulling upon the cable 0 the bucket is raised until stopped by the projection P on the block P coming in contact with the framework of the traveler. Then by manipulating the gear V the traveler is released and will commence to travel along the cable G by gravity, and as soon as it is clear of the trip U the spring-pawl T will enter into engagement with the ratchet-wheel T and prevent any .retrograde movement of the ratchetwheel. Then by paying out the cable 0 the travelerwill be allowed to descend along the cable G to its destination, and when this is reached the operator at that end can release the pawl T by pulling the rope \V and by still further paying out the cable 0. The bucket then will be allowed to descend and can be emptied, and, the signal being given, the operator upon the vessel to which the apparatus is attached will begin winding up the cable 0, which will first raise the bucket to the limit of its movement, and as the cable 0 e011- tinues to wind up the traveler H will be drawn along the cable G, and when it springs the latch V will be automatically locked in place and the pawl T automatically removed from the ratchet-wheel. Thus it will be seen that a very simple, complete, durable, and eificient apparatus is provided whereby vessels can be coaled at sea, even in stormy weather, and can remain at a considerable distance from one another, so as to be in no danger of collision.

Of course I do not wish to be limited to the exact construction here shown, as slight modi 'fications could be made without departing from the spirit of my invention.
